ASTM A572 Gr. 55 mild steel plates application and meansures for oxide iron skin

ASTM A572 Gr. 55 mild steel plates are widely used as bridge plates, bearing plates, machine mounting plates, etc for construction equipment, transmission towers, machine frames., etc equipment.

ASTM A572 Gr. 55 mild steel plates are easy to form oxide iron skin on the plate surface. With long term experience and test, BBN steel has find some solutions as below:

1) Reduce heating temperature of ASTM A572 Gr. 55 mild steel slab, so as to reduce the production of A572 Gr. 55 steel slab oxide iron skin in the heating furnace.

2) In the case of ensuring ASTM A572 Gr. 55 mild steel plates quality, use the plate coil box as far as possibleThe plate coil box can peel off the oxide iron skin generated in rough rolling area during the process of taking the middle ASTM A572 Gr. 55 mild steel billet.

3) Properly increase the cooling water between the racks, speed up the rolling speed of ASTM A572 Gr. 55 mild steel, and inhibit the production of oxide iron skin.

If you are facing the oxide iron skin problems of ASTM A572 Gr. 55 mild steel plates, you may try above measures also, which are proved effective in practice.
